mḥámmad eb ˁan áḥmad ‘Muhammed is bigger than Ahmad.’ (Kogan 2015:487)

As recognized long ago (Müller 1909:347–351, Bittner 1918a:54), the Soqotri/Jibbali gender-suppletive adjectives for “big” cannot be separated from the PS designations of “father” (*ˀab-) and “mother” (*ˀimm-), from which, however, they differ in their synchronically attested shapes. The diachronic background of this unusual phenomenon remains enigmatic (Kogan 2015:592).
